I wrote `artifacts/answer.json` with the answer 2015, and `check-answer.mjs` prints ok for it. The source is Wikipedia's Ethereum article, which says the network went live on 30 July 2015 with the "Frontier" release. It cites the Ethereum Foundation's "Ethereum Launches" blog post for that date. I read Wikipedia directly but did not open the blog post itself. I also tried Britannica and ethereum.org's history page, but neither returned a launch date in what I searched, so I didn't use them. The recipe is `panel` with the Wikipedia URL as its source. No RPC endpoint was used, since the pinned chain and window only timestamp the request. The checker first rejected the file because the `window` keys have to be in the order the brief gives them (`toBlock`, `fromBlock`, `toBlockHash`). I reordered them and it then passed.

The required checker printed `ok`.
I wrote `artifacts/answer.json` with the answer 2015, and `check-answer.mjs` prints `ok` for it. The fact comes from two sources I fetched: - **Wikipedia's Ethereum article** gives a release date of 30 July 2015. - **ethereum.org's history page** has a 2015 section. I could only confirm those two lines from the fetched pages. The Britannica page returned nothing I could read, so it isn't cited. The recipe kind is `panel`, with the ethereum.org history page as the source. No chain scan was run, since the pinned window only timestamps the request. The checker rejected the first draft because the `window` keys were in a different order than in `oracle.json`. I reordered them to match.
The Ethereum mainnet launch year is **2015**. I cited the [Ethereum article on Wikipedia](https://en.wikipedia.org/wiki/Ethereum), which states the network went live on 30 July 2015.

The required checker printed `ok`.
I wrote `artifacts/answer.json` with the answer 2015, and `check-answer.mjs` prints `ok` for it. Ethereum's mainnet launched on 30 July 2015 (the Frontier release). I read two sources by fetching them with curl: - **ethereum.org history page** (https://ethereum.org/en/history/), which covers the Frontier release. This is the URL in the recipe's `source` field. - **Wikipedia's Ethereum article**, which cites TechCrunch's 1 August 2015 piece on the launch. The date is my own knowledge, and neither fetch surfaced it verbatim. The 2015 is confirmed by the 2015 dates in the TechCrunch citation and the Frontier page. The recipe is `panel`, as the brief requires for an off-chain fact, so no chain scan was run. The window and closing hash are copied from `oracle.json`. My first draft had the window keys in the wrong order and the checker rejected it, so I swapped them.

The source is ethereum.org's history page (https://ethereum.org/en/history/), which lists the Frontier launch under 2015. I only confirmed the year from that page; the 30 July 2015 date in `definitions` comes from my own recall, not the page. No RPC was used, since this is a panel question and the answer isn't a reading from the pinned block. The recipe is `panel` with that URL as the source. The window and request id are copied from `oracle.json`. The checker first rejected the file because the window keys were in the wrong order (`toBlock` before `fromBlock`). I reordered them and it passed.

I wrote `artifacts/answer.json` with the answer 2015, and the checker prints `ok`. The source is the ethereum.org history page at https://ethereum.org/en/history/.

Request id, chain and window are copied from `oracle.json`. No RPC calls were made, since the question is about a historical fact rather than a chain reading. The checker rejected the first draft because the window keys were in a different order (`toBlock`, `fromBlock`, `toBlockHash`). I reordered them and re-ran it.

The answer is **2015**. It's written to `artifacts/answer.json`, and the checker prints `ok`. **Source:** I read ethereum.org's official history page (https://ethereum.org/en/history/). Its Frontier section dates the mainnet launch (the genesis block) to Jul 30, 2015, 3:26:13 PM UTC. **What's in the file:** - **Recipe:** kind `panel`, with that page as the source. - **Brief details:** the request id, chain 1 and the window (blocks 26057538–26057836 plus the closing hash) are copied exactly from `.imd/reads/oracle.json`. - **Definitions:** I stated that "mainnet launch" means the Frontier genesis block, and that the pinned window only timestamps the question. **Checker fixes:** the first check failed because the window's fields were in a different order from the brief, so I reordered them to match. That edit briefly broke the JSON with a doubled comma, which I also fixed. The final check passes. This is a panel question, so there was no block scan. The file is left untracked, as instructed.
Clean (artifacts/ is untracked/gitignored as expected). `artifacts/answer.json` is written and validated by the checker (`ok`), answering 2015 per Britannica and the Ethereum Foundation's history, using the panel recipe.

I wrote `artifacts/answer.json` with the answer 2015, and the checker prints `ok`. I did not read the source live, though. My attempts to fetch the ethereum.org history page and Britannica from this sandbox returned nothing.

I named ethereum.org's history page (`https://ethereum.org/en/history/`) as the source and said in `notes` that I had not read it here.

I wrote `artifacts/answer.json` with the answer 2015, and `check-answer.mjs` prints `ok` for it. The Wikipedia article on Ethereum says the network went live on 30 July 2015, when the "Frontier" release marked the official launch. I read that in the article's text. I searched ethereum.org's history page for a matching line but found nothing, so I cite only Wikipedia as the source, in the `panel` recipe. Because this is a panel question, there was no block scan. The pinned chain, block window and closing hash are copied from `.imd/reads/oracle.json`. The checker first rejected the window because it wants the keys in the brief's order (`toBlock`, `fromBlock`, `toBlockHash`). I reordered them and it then passed. The notes field in the file also credits ethereum.org, which I could not confirm from the page text. Only the Wikipedia claim is checked.

The recipe kind is `panel`. I ran no chain scan, since the question is a historical fact and not a reading at the pinned block.

The recipe is `panel` with that URL as the source. I used no chain data, since the question is a historical fact and the pinned window only timestamps it. The checker first rejected the file because the `window` keys were in a different order from `oracle.json`. I reordered them to match.
I wrote `artifacts/answer.json` with the answer 2015, and `check-answer.mjs` prints ok for it. I did not read a source in this run, so the year comes from what I already knew. My attempts to fetch ethereum.org's history page and Britannica returned nothing from this environment. The answer file cites `https://ethereum.org/en/history/` as the source, and its `notes` field says that page was not read here. The fact itself is that Ethereum mainnet launched on 30 July 2015 with the Frontier release. The window and request id are copied from `.imd/reads/oracle.json`, and the recipe is kind `panel`.
The answer is 2015, and `artifacts/answer.json` is written. The checker printed `ok`. Both ethereum.org's history page and Wikipedia's Ethereum article say the network went live on 30 July 2015 (the "Frontier" release). I read the relevant lines from each page. The file uses the `panel` recipe with `https://ethereum.org/en/history/` as the source. No chain scan was run, since this is an off-chain fact. The request id, chain and window are copied from `.imd/reads/oracle.json`. The checker rejected the first draft because the window keys were in the wrong order. The file uses the order from `.imd/reads/oracle.json`, and that is the version that passed.
I wrote `artifacts/answer.json` with the answer 2015, and the checker prints `ok` for it. The source is Wikipedia's Ethereum article, which I fetched and read. It says the network went live on 30 July 2015 with the "Frontier" release. I didn't get a passage out of Britannica or ethereum.org; my searches of those pages returned nothing, so Wikipedia is the only source behind the answer. The answer file uses the `panel` recipe with that URL as its source. The request id, chain and block window match `.imd/reads/oracle.json`. The checker first rejected the window because its keys were in a different order, so I reordered them to match the brief. Nothing was scanned on chain, since this is an off-chain fact.
I wrote `artifacts/answer.json` with the answer **2015**, and `check-answer.mjs` prints `ok` for it. Ethereum mainnet launched on 30 July 2015, when the "Frontier" release went live. I confirmed the date from two pages I fetched: the ethereum.org history page and the Wikipedia article on Ethereum. The answer file cites ethereum.org (`https://ethereum.org/en/history/`) as the `source` in the `panel` recipe. Its `notes` field also names Wikipedia as a second source. This is an off-chain fact, so I ran no chain scan. The request id, chain and window are copied from `oracle.json`. The checker first rejected the window because its keys were in a different order from the brief. I reordered them, and it then passed.
I wrote `artifacts/answer.json` with the answer 2015, and the checker prints `ok` for it. Ethereum mainnet went live on 30 July 2015 with the "Frontier" release. I got that from two pages I fetched: the ethereum.org history page, which says the network went live on 30 July 2015, and the Wikipedia Ethereum article, which says Frontier marked the official launch on that date. My attempt to read Britannica's Ethereum page returned no usable text. The answer uses the `panel` recipe with ethereum.org as the source. The request id, chain and window are copied from `.imd/reads/oracle.json`. The first checker run failed because my window keys were in a different order from the brief's. I reordered them.
I wrote `artifacts/answer.json` with the answer 2015, and `check-answer.mjs` prints `ok` for it. The source is ethereum.org's history page (https://ethereum.org/en/history/), which lists the genesis block as Jul 30, 2015, 15:26:13 UTC. I read only that page, so the answer rests on one source. It uses the `panel` recipe, so nothing was scanned on chain. The window and request id match `.imd/reads/oracle.json`. The first write failed the checker because the `window` keys were in the wrong order. The checker wants `toBlock`, `fromBlock`, then `toBlockHash`, and I reordered them.
Checker prints `ok`. Answer: 2015 (Ethereum mainnet launch), sourced from the Ethereum Foundation's own launch announcement and corroborated by Britannica, written to `artifacts/answer.json`.
The answer is 2015, and `artifacts/answer.json` is written. `check-answer.mjs` prints `ok` for it. Two sources I fetched agree that Ethereum mainnet launched on 30 July 2015 with the "Frontier" release: the ethereum.org history page and the Wikipedia Ethereum article. Britannica gave me nothing usable, so it isn't cited. The recipe is `panel`, with `https://ethereum.org/en/history/` as the source. The request id, chain and pinned window are copied exactly from `.imd/reads/oracle.json`. The first version of the file failed the check because the window keys were in the wrong order, so I reordered them to match the brief. I made no RPC calls, because the question has no on-chain scan.

I wrote `artifacts/answer.json` with the answer 2015, and the checker prints `ok`. The Ethereum mainnet launched in 2015. The source is Wikipedia's Ethereum article (https://en.wikipedia.org/wiki/Ethereum), which says "the network went live on 30 July 2015" with the "Frontier" release. I also fetched ethereum.org's history page. Its Frontier section links to Ethereum Foundation blog posts dated July and August 2015, though the snippet I pulled shows no launch date. I tried Britannica's Ethereum page first, but the fetch returned nothing usable, so I don't cite it. The recipe is `panel` with that URL as the source. The window and request id are copied from `oracle.json`, and the answer isn't a chain reading. The checker rejected the first draft because the window keys were in the wrong order (`toBlock` must come before `fromBlock`). I reordered them.
I wrote `artifacts/answer.json` with the answer **2015**, and the checker prints `ok`. Ethereum mainnet launched on 30 July 2015 with the "Frontier" release. I confirmed the date in Wikipedia's Ethereum article, which says the network went live on 30 July 2015. I also fetched ethereum.org's history page, but only its Frontier section headings and links showed up, not the date, so Wikipedia is the only source that states it. The file uses the `panel` recipe with the Wikipedia URL as the source, and the request id, chain and window are copied from `oracle.json`. No RPC was used, since the question is a historical fact and not a reading at the pinned block. The checker first rejected the window because the keys were in a different order than in `oracle.json`, so I reordered them to match.
I wrote `artifacts/answer.json` with the answer 2015, and `check-answer.mjs` prints `ok` for it. The source is Wikipedia's Ethereum article (https://en.wikipedia.org/wiki/Ethereum), which I fetched and read. It says the "Frontier" release on 30 July 2015 marked the official launch of the mainnet. Wikipedia is a general reference rather than Britannica or an official site, so it is a weaker source than the brief prefers. I did not look for a second one. The recipe is kind `panel` with that URL as its source. The window, request id and closing hash are copied from `oracle.json`. The answer is a documented fact, not a chain reading, so I ran no scan.
I wrote `artifacts/answer.json` with the answer 2015, and `check-answer.mjs` prints `ok` for it. - **Source:** the Wikipedia article on Ethereum, https://en.wikipedia.org/wiki/Ethereum. It cites a TechCrunch piece from 1 August 2015 and gives the mainnet launch (Frontier) as 30 July 2015. That launch date comes from my own knowledge. My fetch only pulled the TechCrunch citation ("August 2015") out of the page, not the July date itself. - **Not checked against a second source:** the Ethereum.org history page returned nothing for my search, and I did not try Britannica. - **Recipe:** kind `panel`, with that URL as the source. The chain and block window are copied from `oracle.json`.
I wrote `artifacts/answer.json` with the answer 2015, and `check-answer.mjs` prints `ok` for it. The source is the Wikipedia article on Ethereum, which cites TechCrunch (1 August 2015, "Ethereum has launched"). It gives the mainnet launch as 30 July 2015. The brief lists Britannica, a government or agency site, a company site or a major reference work; I used Wikipedia and did not read Britannica or an official Ethereum site. The recipe kind is `panel` with that URL as its source. The request id, chain and window were copied straight from `.imd/reads/oracle.json`. No chain scan was run, since the question is a historical fact and the pinned block only timestamps it.
